An improved algorithm of two dimensional convex hull based on included angle is proposed, and all the convex points are achieved through the maximal included angle by the increasing counter-clockwise direction. When more than one point satisfies the maximal included angle, the most distant point to the previous point is regarded as the next convex point.

Angle of view: With 60 degs. apparent angle of field, the DF and the IOR are the only wide angle binoculars in this test.

视角：在本评测中，DF和IOR有60度表现视场，是仅有的广角望远镜。

Angle of view: These are low light binoculars and one should not expect excessive wide fields of view. Closest to 'wide angle' comes the IOR with 60 degs. apparent angle, which is sufficient to avoid the tunnel-view of its contenders.

视角：这些都是低亮度望远镜，不能期望有极宽广的视角，最接近"广角"的当属有60度表现视场IOR，远离了只有管窥视野的其它两款。

The forward kinematics is analyzed by choosing one of the mechanisms which have one, two,three or zero angle constraint.Wherein,3-CCC is a new parallel mechanism which has three angle constraints and three distance constraints, Calay\'s formular and direction cosine matrix are used to describe the rotation matrix respectively.By setting Dixon\'s and Sylvester\'s resultant with the three angle constraint equations respectively and using parameters replacement to deal with the distance constraint equations,the 64 order input-output equation of the forward kinematics is obtained under both of the methods.Numerical example confirms these theretical results and the motion simulation is shown in VC++ by integrating OpenGL.
